Specific tariff classification for computer accessories prevails over general plastic heading for specially designed mouse pads.

Mouse pads specially designed for use with a computer mouse were classified as computer accessories under Heading 8473.30 rather than as plastic articles under Heading 3921.13. The more specific tariff entry prevailed over the broader plastic description, and Rule 3(a) of the Interpretative Rules supported the specific classification. The HSN explanatory notes were treated as persuasive guidance in resolving the dispute. The computer-accessory classification was upheld and the Revenue's challenge failed.

Issues: Whether mouse pads were correctly classified under Heading 8473.30 as accessories of computers, or under Heading 3921.13 as plastic articles, and whether the HSN explanatory notes and the rule of specific classification governed the dispute.

Analysis: The item was found to be specially designed for use with a computer mouse and to assist the computer in performing its intended function. The explanatory notes to the HSN were treated as having persuasive value, and the more specific heading was preferred over the general description. Rule 3(a) of the Interpretative Rules also supported adoption of the more specific classification.

Conclusion: The classification under Heading 8473.30 was upheld and the Revenue's challenge failed.

Ratio Decidendi: Where goods are specially designed as computer accessories, the specific tariff heading prevails over a broader plastic classification, and HSN explanatory notes may be relied upon as persuasive guidance in classification.
